Wi-Fi Installation for Construction Sites & Temporary Compounds

Wi-Fi Installation for Construction Sites

Construction sites are fluid: cabins move, compounds shift, steel goes up, and the workforce scales by the week. Yet the need is constant—stable site Wi-Fi for office cabins, tablets, PoS, scanners, CCTV towers and visitors. If the wireless falters, drawings don’t sync, inductions stall and supervisors burn time on hotspots. ACCL delivers survey-led, construction-ready Wi-Fi across London, Surrey and Kent, built to cope with changing layouts, tough conditions and tight programme windows.

Why site Wi-Fi struggles (and how we fix it)

  • Shifting layouts & steel: New steelwork and stacked cabins change RF paths daily. We design modular cells and spare outlets so APs can be re-sited without rework.

  • Backhaul bottlenecks: Single 4G routers saturate at peak; long copper runs drop speed. We specify bonded 4G/5G, leased line or fibre where available, and certify the wired layer end-to-end. (See our core Wi-Fi Installation overview.)

  • Power & enclosure issues: Condensation, dust and knocks kill consumer kit. We use ruggedised APs/enclosures, correct PoE, and weather-rated gear for external walkways and yards.

  • Flat networks = risk: Guest, contractor and site operations must be separated to protect systems and keep airtime fair.

  • Messy, hot cabinets: Over-long patching and poor airflow cause random drops. A cabinet tidy stabilises day-one performance. (Quick win: Data Cabinet Tidy.)

Our survey-led, modular approach

1) Kick-off & phasing plan
 We meet PM, Site Manager and H&S to map compound layout, cabin stack plans, welfare blocks, turnstiles, CCTV towers and programme phases. We agree out-of-hours windows and permits.

2) Backhaul design
 We benchmark options: bonded 4G/5G, fixed fibre/leased line, or a mix by phase. Where compounds are split, we connect them with engineered point-to-point wireless links (primer: Point-to-Point Wireless Links).

3) Structured cabling & PoE
 We install standards-aligned cabling within cabin blocks and to outdoor APs, label everything, and certify links—so moves, adds and changes are fast and low-risk. (Foundation detail: Structured Data Cabling.)

4) RF design for changing sites
 AP counts and placements suit stacked cabins, welfare, canteens and yard coverage. Channel width/power and minimum data rates are tuned for fair airtime; 802.11k/v (and 11r where supported) smooth roaming.

5) Secure segmentation
 Separate SSIDs/VLANs for Staff/Contractors, Guest/Visitors, Ops/IoT (CCTV/signage) and PoS where applicable. 802.1X for corporate devices; rate-limited guest access.

6) Install, validate & handover
 Noisy works out-of-hours; validation under real loads; handover pack with heatmaps, as-builts, patching matrices, PoE budgets and controller backups. For ongoing changes, our team delivers swift MACs. (Operational support: Wireless Network Installation & Support.)

What your finished solution includes

  • Rugged APs & enclosures for cabins, stair cores and external walkways; outdoor-rated units for yards and turnstiles.

  • Backhaul that scales: bonded 4G/5G with high-gain antennas where fibre’s not ready; seamless cut-over to fixed circuits when they land.

  • Clean, certified cabling—correct category runs, labelled outlets, compliant containment and ventilated cabinets.

  • Controller policies—SSIDs, VLANs, guest portal, QoS and monitoring so issues surface before they bite productivity.

  • Re-site-ready design—spare outlets and documented pathways so cabins and APs can move with the programme.

If foundations are unknown, begin with a light-touch Cabling & Network Audit.

Safety, compliance & site protocols

  • RAMS & permits for working-at-height, segregated zones, dust/noise control and hot works.

  • Fire-stopping & LSZH: penetrations reinstated to maintain compartmentation; low-smoke materials where required.

  • Secure equipment: locked comms cabinets, tamper-resistant fixings and health alerts on outages.

  • Data protection: guest isolation, named admin access and MFA; sensible retention for any controller logs.

If you’re also deploying towers or monitored cameras, we align Wi-Fi and cabling with your security stack (compare CCTV Installations and Commercial Access Control Installation).

Benefits for PMs, Site Managers & QS

  • Predictable connectivity for drawings, inductions, emails and Teams—even at sign-on peaks.

  • Fewer callouts thanks to certified links, tidy cabinets and controller visibility.

  • Faster moves as cabins re-stack; documented outlets and spare capacity speed re-sites.

  • Lower lifetime cost by avoiding ad-hoc routers and emergency fixes; reusable templates for the next project.

  • Future-ready—designs anticipate more devices, additional cabins and fixed backhaul when available.

FAQs

We don’t have fibre—can you still deliver reliable Wi-Fi?
 Yes. We often start with bonded 4G/5G and high-gain antennas, then cut over to fibre/leased line when live.

Can you cover large yards and remote compounds?
 Yes—engineered point-to-point links extend LAN/Wi-Fi across service roads and yards, with proper lightning protection.

Will noisy works disrupt the site?
 No. Heavy tasks are out-of-hours; daytime works are low-impact and zoned. Each area is reinstated daily.

Do we need to re-cable when cabins move?
 No. We pre-plan spare outlets and pathways; APs and switches can be re-sited quickly with minimal rework.

Can we segregate contractors and visitors?
 Yes—distinct SSIDs/VLANs with policy controls; guest portals as simple or branded as you need.

Do you provide documentation?
 Every project hands over heatmaps, as-builts, patching matrices, PoE budgets and controller backups.

Next steps

If inductions buffer, drawings won’t sync, or CCTV drops whenever the compound moves, it’s time to fix the foundations.

Book a no-obligation construction site Wi-Fi survey and we’ll show what to reuse, what to change and how to deliver stable, modular wireless that keeps the programme moving.
